Description

Technical Field

[0001] This utility model belongs to the field of shear wall casting technology, specifically relating to a quick-release shear wall column combined formwork structure. Background Technology

[0002] A shear wall, also known as a wind-resistant wall, earthquake-resistant wall, or structural wall, is a wall in a building or structure that primarily bears horizontal and vertical loads (gravity) caused by wind or earthquakes, preventing structural shear failure. It is typically made of reinforced concrete.

[0003] A domestic utility model patent application with application number 202322911977.6 discloses a formwork for structural columns at the ends of shear walls, used for processing structural columns at the ends of shear walls. The structural column formwork includes a formwork assembly and a reinforcement assembly. The formwork assembly includes a formwork, reinforcing bars, and timber. The reinforcement assembly includes a detachably connected first component, a second component, and a connector. The formwork is fitted to the structural column against the shear wall. The formwork contains the reinforcing bars required for column forming. The first component passes through a trapezoidal hole in the second component, and a pin is detachably inserted into the positioning groove of the first component, so that the connected first and second components are tightly fitted with the timber on the outside of the formwork. The timber presses the formwork. The connector, which passes through the shear wall, connects the first and second components through a first limiting hole and a second limiting hole, respectively, so that the reinforcement assembly is relatively fixed to the shear wall. Multiple sets of reinforcement components are spaced apart to fix the position of the timber and formwork relative to the shear wall, which can avoid the problems of poor formwork stability and easy grout leakage during pouring, resulting in poor quality of structural column forming. The above-mentioned utility model requires on-site assembly of components, and bolt fixing of corresponding support structures at the external and internal corners is required according to the component assembly position. After the pouring is completed, the components need to be disassembled in sections. The installation and disassembly steps of the support structures at the external and internal corners are cumbersome and prolong the disassembly time. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a quick-release shear wall column combined formwork structure, including steel formwork, external corner formwork installed between the outer ring of steel formwork, internal corner formwork installed between the inner ring of steel formwork, a docking frame fixedly installed on the steel formwork for positioning and tie rods, a support frame fixed between the docking frames at the position of the external corner formwork, and a clamping frame fixed between the docking frames at the position of the internal corner formwork. The steel formwork and the docking frame are fixedly installed by the mounting frame, and a reinforcing cage for pouring is provided between the inner and outer sides of the steel formwork.

[0005] As a further preferred technical solution of this utility model; the docking frame is provided with a tie groove, the docking frame located in the tie groove is provided with a locking hole, the locking hole is provided with a tie bolt through the steel template, positioning plates are welded and installed on the docking frame at the top and bottom of the tie groove, two sets of mounting plates are welded and installed on the docking frame on the back of the positioning plate, and multiple sets of limiting holes are provided on the docking frame.

[0006] The positioning plate limits the locking end of the tie bolts. When using this combined formwork, the docking frame can be positioned and installed first. The steel formwork and docking frame can be installed directly without the need to assemble with the horizontal beams, vertical beams and plates, reducing the steps before shear wall pouring and increasing the ease of use of this combined formwork.

[0007] As a further preferred technical solution of this utility model, the steel template is symmetrically arranged inside and out, and the inner side of each end of the steel template is provided with a positioning block for limiting the positioning template. Multiple sets of grooves are opened on the outer side of the steel template, and two sets of welding frames are welded and installed on the grooves. Positioning holes are opened between the welding frames on the steel template.

[0008] The welding frame is used to install the connecting frame, and the steel templates are installed by pulling them together through the positioning holes.

[0009] As a further preferred technical solution of this utility model, the mounting frame is provided with a butt plate and a connecting plate at a 90° angle. The connecting plate and the welding frame are fixedly installed by two sets of connecting bolts, and the butt plate and the mounting plate are fixedly installed by fixing bolts.

[0010] The mounting bracket connects the connecting frame and the steel formwork, facilitating flexible use of the connecting frame and allowing for effective adjustment of the position between the connecting frame and the external or internal corner formwork.

[0011] As a further preferred technical solution of this utility model; the support frame is in two sets and is respectively installed at the ends of the two sets of docking frames located at the position of the external corner template. A triangular frame is welded and installed on the support frame. The triangular frame has two sets of through holes. The two sets of support frames are locked and connected by external corner locking bolts through the through holes. The support frame has a hole of the same size as the limiting hole. The support frames are limited and fixed by external corner pins through the support frame and the limiting hole. One end of the support frame is fixed to the docking frame by a stop plate.

[0012] When using the steel formwork, the dimensions of the internal and external corner formwork can be limited according to the required dimensions of the shear wall to be poured. The connecting frame can be pre-installed. After use, when the steel formwork needs to be disassembled, the tie bolts installed between the steel formwork and the connecting frame can be removed directly, and the steel formwork and its outer ring support structure can be disassembled as a whole to achieve a quick disassembly effect, which facilitates the subsequent construction of the shear wall.

[0013] As a further preferred technical solution of this utility model; two sets of symmetrical side plates are welded and installed on the clamping frame, and a support plate is welded and installed on the side plate. Insertion holes are opened on the side plates, and the insertion holes are locked together by a corner locking bolt. The support plate is opened with a through hole of the same diameter as the limiting hole, and the support plates are fixed together by a rod passing through the support plate and the limiting hole.

[0014] By using clamping frames and support frames in conjunction with steel formwork, the positions of the internal and external corner formwork are positioned to ensure the completion of concrete pouring. At the same time, the dismantling steps can be reduced during dismantling, and the steel formwork and its outer ring support structure can be dismantled directly, thus completing the quick dismantling of the formwork.

[0018] 2. By using clamping frames and support frames in conjunction with steel formwork, the internal and external corner formwork positions are positioned to ensure the completion of concrete pouring. This also reduces the number of dismantling steps during removal; the steel formwork and its outer support structure can be dismantled directly, enabling quick formwork removal. Furthermore, the installation of the connecting frames, support frames, and clamping frames is simple and involves few steps. This optimizes formwork removal time and significantly improves project efficiency. Attached Figure Description

[0026] The utility model mentioned above requires on-site assembly of components, and bolts need to be used to fix the corresponding support structure at the external and internal corners according to the assembly position of the components. After the pouring is completed, the components need to be disassembled in sections. The installation and disassembly steps of the support structure at the external and internal corners are cumbersome and prolong the disassembly time.

Two sets of installation plates 35 are welded and installed on the connecting frame 3 on the back of the positioning plate 32. Multiple sets of limiting holes 33 are provided on the connecting frame 3. The positioning plate 32 limits the locking end of the tie bolt 15. When using this combined formwork, the docking frame 3 can be positioned and installed first. The steel formwork 1 and the docking frame 3 can be installed directly without the need to assemble with the horizontal beams, vertical beams and plates, reducing the steps before the shear wall is poured and increasing the convenience of using this combined formwork.

[0028] The steel formwork 1 is symmetrically arranged inside and out. Positioning blocks 14 for limiting the positioning of the template are provided on the inner side of each end of the steel formwork 1. Multiple sets of grooves 11 are formed on the outer side of the steel formwork 1, and two sets of welding frames 13 are welded and installed on the grooves 11. Positioning holes 12 are formed between the welding frames 13 on the steel formwork 1. The welding frames 13 are used to install the connecting frame 3, and the positioning holes 12 are used to connect the steel formwork 1. The mounting frame 2 has a 90° connecting plate 21 and a connecting plate 22. The connecting plate 22 is fixed to the welding frame 13 by two sets of connecting bolts 23, and the connecting plate 21 is fixed to the mounting plate 35 by fixing bolts. The mounting frame 2 connects the connecting frame 3 and the steel formwork 1, facilitating the flexible use of the connecting frame 3 and allowing for effective adjustment of the position between the connecting frame 3 and the external corner template 5 or the internal corner template 4.

[0029] Two sets of support frames 6 are installed at the ends of the two sets of connecting frames 3 located at the external corner formwork 5. A triangular frame 61 is welded onto the support frame 6, and two sets of through holes 62 are opened on the triangular frame 61.

The clamping frame 7 and support frame 6, in conjunction with the steel formwork 1, position the internal corner formwork 4 and external corner formwork 5, ensuring the completion of concrete pouring. Simultaneously, it reduces the number of disassembly steps during disassembly, allowing direct disassembly of the steel formwork 1 and its outer ring support structure, thus enabling quick formwork removal. Furthermore, the installation method of the connecting frame 3, support frame 6, and clamping frame 7 is simple and involves fewer steps. This optimizes the formwork removal time and significantly improves project efficiency.

The connecting frame 3 is pre-installed, eliminating the need for assembly with horizontal and vertical beams and panels, thus reducing pre-pouring steps. The clamping frame 7 and support frame 6, in conjunction with steel formwork 1, position the internal corner formwork 4 and external corner formwork 5, ensuring the completion of concrete pouring. Simultaneously, dismantling can be streamlined by directly removing steel formwork 1 and its outer supporting structure, enabling quick formwork removal. Furthermore, the installation of the connecting frame 3, support frame 6, and clamping frame 7 is simple and involves few steps. This optimizes formwork removal time and significantly improves project efficiency.
